- W2050497706 abstract "Oxygen K near-edge spectra measured by fluorescence were obtained for fully oxidized and oxygen-deficient YBa2Cu3O7−δ (1:2:3) and La2−xSrxCuO4−y (2:1:4). Two features occur just above the Fermi level, one near 530 eV (hybridized states) and the other near 528 eV (oxygen 2p holes). For 1:2:3 the oxygen dependence of energy and intensity of the two peaks is determined. The oxygen hole peak intensity has a constant non-zero value for 6.27≤(7−δ)≤6.40 where the superconducting transition temperature Tc is below 5 K, then rises (as does Tc) as the oxygen content increases toward 7. These results are correlated with earlier Cu K edge measurements which determined the Cu1+ content of similar samples. These quantitative bulk results can also be used as a calibration for estimating the local oxygen content of the microstructure (e.g., grain boundaries) using electron energy loss spectroscopy. We also report oxygen K edge measurements of standard and oxygen-reduced 2:1:4 well into the “overdoped” region (0.35≤x≤0.60), and compare these results with those for 1:2:3." @default.
